Installing the Media Converter
The following procedure explains how to install the media converter as a
standalone unit.
If you are building a back-to-back installation, please review the following.
See Figure 5 for an illustration of a back-to-back-media converter
configuration.
❑ During installation, setup, and testing of back-to-back media
converters, make sure each media converters Link Test/MissingLink
button is in the LNK TST (OUT) position.
❑ When two media converters are connected back-to-back with no UTP/
STP cables connected and when the LNK TST button is in the OUT
position (link test mode), the ACT LEDs on the fiber port may flash.
This is normal and will not affect the normal operation of the units.
To install the unit, perform the following procedure:
1. Remove all equipment from the package and store the packaging material
in a safe place.
2. If you are installing the unit on a desktop, attach the four rubber feet to
the base of the unit, placing one rubber foot in each corner. If you are
installing the unit in an AT-MCR12 chassis or AT-TRAY4 tray, do not
attach the rubber feet.
3. Set the Link Test/MissingLink button to LNK TST (OUT) position.
4. Set the auto-negotiation feature as follows:
— If both end nodes will use auto-negotiation to determine the duplex
mode, or if both are pre-set to operate with the same duplex mode,
such as half-duplex, set the switch to the A/N ON (IN) position. This
is the default setting.
— If one end node is capable of operating at only half-duplex mode while
the other node will determine its duplex mode through auto-
negotiation, set the switch to the A/N OFF (OUT) position.
5. If you are installing the unit in an AT-MCR12 chassis or AT-TRAY4 tray,
refer to the appropriate installation guide for instructions on how to
install the media converter into the unit.
